Title: Geared drum cam switching mechanism - has precision reduction gear to drive drum from central shaft
Inventor: JAKOB LUDWIG ING GRAD
IPC: H01H19/18
Filed: 1980-11-29
Abstract: The switch drum unit is typically the final drive unit in a geared down machine drive assembly. The drive is a precision assembly. The drum has around its surface the various cams which operate the switch mechanisms. The main drive shaft powers the drum through a reduction gear arrangement. The machine drive to the central shaft of the reduction gear is a close tolerance play-free no-torsion coupling, but it has an elasticised component to ensure correct axial transmission from machine to reduction gear primary shaft. For precision the reduction gear is also spring tensioned and with the minimum inherent play but the spring biassing ensures precision and accurately repeatable switch operation. The final cam drum is mounted on a roller bearing.

Title: Covering for etuis, boxes or cases
Inventor: FONTANNAZ MARCEL
IPC: A45C13/08
Filed: 1981-02-17
Abstract: The covering (2) for etuis, boxes or cases is removable. It has side walls (3) which widen in such a way that the edge (7) of these walls spreads away from the side walls (4) of the etui. In contrast thereto, the opposite edge (8) rests firmly against the etui and holds the covering fixed to the etui by elasticity. In this way, the covering can easily be fitted on and removed by simple pressure and pulling. The etui, the box or the case (11) is provided with a removable covering (12). The etui is made of two parts which fit one inside the other. The edges of each of the two parts have a projecting edge strip (14). A groove (16) is formed in said edge strip. The edge (15) of the side wall of the covering is received in this groove. The rough points, the burr and the defects of the edge (16) are removed from sight in this way. The material from which the covering is produced is a polystyrene which is covered with a layer produced from acrylic fibres which are thrown or twisted in such a way that they look like flocks of dust, and which, lying bonded and compressed, are mixed with a thermoplastic adhesive which sticks to polystyrene. This material has a velvety appearance which is very similar to that of suede leather. <IMAGE>

Title: Door-actuating device
Inventor: SCHNEIDER STEFFEN
IPC: E05F15/50
Filed: 1981-05-08
Abstract: What is proposed is a door-actuating device which is provided with a door valve (9) for the compressed-air-actuated to-and-fro movement of a door (1) and with an emergency valve (17), by means of which the two working chambers (5 and 6) of the working cylinder (4) moving the door (1) can be made pressureless, in order to actuate the door (1) by hand. The emergency valve (1) has two locks (20/21, 33/34), of which one (20/21) can be actuated mechanically and the other (33/34) electromagnetically. This ensures that, although a change-over from power operation to manual operation can be brought about in any operating position of the door, nevertheless a change-over from manual operation to power operation is conversely possible only when first the mechanical lock (20/21) is released and then, as a result of the actuation of the door valve (17) by the driver, a circuit for cancelling the electromagnetic lock (33/34) is closed. The possibility of jamming in the region of the door as a result of the actuation of the emergency valve (17) from outside through the open door (1) is consequently prevented. <IMAGE>
